Gene Synthesis Over 5 kb

Sequences over 5 kb require specialist providers or multi-fragment assembly. Very few providers offer direct synthesis at this length. Here is a comparison for a representative 8000 bp sequence.

Frequently asked questions

Who can synthesise genes over 5 kb?

Elegen supports linear DNA up to 7 kb and plasmid DNA up to 15 kb. For longer constructs, you may need to order multiple fragments and assemble them in your lab using Gibson Assembly or Golden Gate cloning.

What is the most cost-effective approach for very long genes?

For genes over 5 kb, ordering multiple overlapping fragments from a low-cost provider (Twist or IDT at $0.07/bp) and assembling them yourself is often cheaper than paying a single provider for end-to-end long gene synthesis.
